A Christian-owned chain of hobby shops is facing a bitter backlash after suing the Obama administration over new requirements to provide insured employees with contraceptive and abortion coverage.

Oklahoma-based Hobby Lobby filed the suit Sept. 12 in U.S. District Court in Oklahoma City, alleging that the ObamaCare mandate violates the religious beliefs of the company’s owners. The suit followed similar suits by Catholic colleges and a Denver-based company whose owners also objected to the mandate on religious grounds. While a judge has not yet ruled on Hobby Lobby’s suit, a Facebook page calling for a boycott of the company, which operates 500 stores in 41 states, has appeared online, and several other forums have featured posts urging customers to steer clear of Hobby Lobby.
